HYMENOPTEROUS PARASITES. 1885 



in the hind legs the $ $ extreme tips of the femora and the whole tibia except the 

 second fourth are black, and the tarsi are pale dusky, often -vvith the base of each joint 

 gradnally a little paler. The areolet of the fore wings is mostly rhomboidal, very 

 rarely subtruncate anteriorly, but never peduncled. Leugth,!^, 3.5-11 mm; $,5-12 ram- 

 (After Walsh.) 



This is a well-known parasite of many lepidopterous larvae. It has 

 been reared from Carpocapsa pomonella, Acrobasis juglandis, Aletia xylina, 

 Grapholitha olivaceana, Coleophora cinerella, Orgyia leucostigma, and other 

 unreared larvae. As a buttei-fly parasite it has been reared but once, viz. : 

 by Mr. J. B. Smith, from a chrysalis of Iphiclides ajax at New York. It 

 is also probably a parasite of Chlorippe clyton. Professor Riley has a 

 pupa of this butterfly which has been broken open, revealing a large 

 ichneumonid pupa which seems to be that of a female Pimpla annulipes. 



Genus GLYPTA Gravenhorst. 



Head transverse, short, cheeks not swollen, entire; clypeusslightly convex, apex round 

 or subtruncate; antennae filiform; eyes nearly entire. Thorax robust; scutellum 

 rounded at tip ; metathoracic spiracles minute, subcircular; legs visually slender, tarsal 

 claws with distinct pectinations, rarely simple or setose internally; wings generally 

 with no areolet, rarely with a complete one. Abdomen sublanceolate or linear, rarely 

 ovate-elongate; joint 1 with a delicate, distinct carina; joints 2 to 4 with two oblique 

 linear depressions ; terebra of female at least as long as abdomen and Issuing from 

 apex ; genital valvules of male usually incrassate, with obtuse apex, rarely narrower 

 with acuminate apex. 



Glypta erratica Cresson. PI. 88, fig. 7. 



Female. — Black, shining; clypens, mandibles, except tips, palpi, tegulae and line be- 

 fore, whitish; antennae brown-black, darker at base, apex and above; wings hyaline; 

 legs, including coxae, yellowish-red; trochanters whitish beneath, posterior pair 

 blackish above ; intermediate tarsi fuscous, pale at base of joints ; base and apex of 

 posterior femora blackish; their tibiae black, with a white stripe above, not reaching 

 the apex and interrupted by a black spot near base, the tarsi black, more or less white 

 at base of joints ; face with a median rounded swelling. Thorax minutely and closely 

 pxmctured ; metathorax rounded, smooth, shining, obsoletely punctured, apex enclosed 

 by a well-defined arcuate carina; abdomen finely and densely punctured, the oblique 

 lines deeply impressed, first segment with two sharply defined, longitudinal carinae at 

 base, becoming obsolete on middle ; venter piceous, ovipositor as long as abdomen. 

 Length, 9 mm. 



Male. — More slender than ? ; the metathorax above has two, more or less distinct, 

 oblique carinae, and the anterior coxae are whitish. Length, 8 mm. (After Cresson.) 



This parasite, which is said by Cresson to be a common species in New 

 York, Delaware, Pennsylvania and West Virginia, was reared by Professor 

 Riley in Missouri from a chrysalis of Polygonia comma. 



FAMILY BRACONIDAE HALIDAY. 



Genus MICRODUS Nees. 



Maxillary palpi 5-jointed, labial 3-or 4-jointed. Face not produced or rostriform. 

 Mesothorax distinctly trilobate. Mesopleura with a rugulose furrow. Three cubital 

 areolets, the first confused with the praediscoidal (after Marshall).
